SharePoint Search Errors

Error1:

Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository. If the repository being crawled is a SharePoint

repository, verify that the account you are using has "Full Read" permissions on the SharePoint Web Application being crawled.( http://samcommunity.qxl.int , http://bpsmerfwwf.qxl.int and http://marketing.qxl.int:8080 )

Reason:

This error will occur, at the time of crawling the SharePoint application content. because, you may have provided a URL to access the SharePoint web application like http://portal.com.au(just an example). If you try http://portal.com.au from the server, you will find you cannot access it at all.

When the search engine tried to crawl the content using the kenportal.com.au URL, the server will reject the request. because, it will take the request as "LoopBackRequest".

Work around:

So we need to disable the LoopBackRequest in registry.

Steps:

1. Go to command window and type regedit.exe

2. Once opened the registry editor, just navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa"

3. Right click on "Lsa" and create a new 32bit DWORD value

4. Rename it as "DisableLoopbackCheck" (Note: you cannot rename it actually. so, once created the DWORD value, directly paste/type as "DisableLoopbackCheck".

5. Then again modify the value of "DisableLoopbackCheck" as "1"

6. Close the registry editor.

7. Now start to crawl the content.

Error2:

This item could not be crawled because the crawler could not connect to the repository.

Suspecting this  issue  from the network firewall side, we need to make sure that all the required ports are opened.

Error3:

The object was not found.( http://us-bos-vwb012  and sps3://us-bos-vwb012)

In our case the object is  http://us-bos-vwb012/   and is not have the  root site. i.e. reason we got the object was not found in the crawl error .

Observations from  Dev Environment  :

Configured the Search functionality for testing purpose  in Dev and  Is working  for  these  sites :

http://server:8020/SitePages/Home.aspx

http://servere:999/

In Dev Env also got the same error (Error1:  Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository.)

Executed the  above workaround (to disable the LoopBackRequest in registry) and  ran the full crawl. after that the Access Denied error resolved in Dev Env.

And from the best practice and security reasons we need to go for a separate Search managed service account to read and crawl  the content in our SharePoint Portal.
